From: Exosomes contribution in COVID-19 patients’ treatment
Exosomes released from Adipose derived stem cells (ADSCs) secrete a panel of growth factors involved in reducing the cytokine storm and rescuing patients from the acute respiratory distress symptoms through the increase in neutrophils and T reg numbers and the polarization of macrophages from M1 to M2 profile. HGF: hepatocyte growth factor, NGF: nerve growth factor, IGF: insulin growth factor, GDF-11: growth differentiation factor-11, IL-10: interleukin-10, TLR-4: Toll like receptor, TGF-β: transforming growth factor-β, TNF-α: tumor growth factor-α, MCP-1: monocyte chemoattractant protein-1, IP-10: induced protein 10, G-CSF: granulocyte colony stimulating factor
